do anyone have any experience configuring these Time off settings options

Here are some things I'm hoping can be changed in our company's settings: 1) allow time off to be booked on company holidays 2) allow time off to be booked on weekends (Saturday & Sunday) 3) allow time off to be taken in different time increments (instead of only 8 or 4 hour options) - allow for varied shifts - some work 10 or 12 hours which will need to allow for half day options, too (5 and 6 hours)

Are you using our shift scheduling functionality to manage their schedules? If not, you can set up an alternate office schedule for those employees which is either 10 or 12 hours per day. Then when you set up a half day holiday, it will use 5 or 6 hours.

Here's a help topic that outlines how to set up office schedules. Once you've set them up, you can assign it to users in the Schedule section of the user profile.

Let me know if that helps with item 3. You could also potentially use that for addressing item 2. If you have hours scheduled on Saturday/Sunday, time off will treat them as normal days. Our team would probably need to help assess whether there are other implications of this change, depending on how you are using our system.
